FIG. 1 is a block diagram illustrating an electronic device and a wearable device, according to an embodiment.

Referring to FIG. 1 , according to an embodiment, an electronic device 100 may include at least one processor 110 and a communication circuit 120 electrically connected with the at least one processor 110. The processor 110 may include a microprocessor or any suitable type of processing circuitry, such as one or more general-purpose processors (e.g., ARM-based processors), a Digital Signal Processor (DSP), a Programmable Logic Device (PLD), an Application-Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), a Graphical Processing Unit (GPU), a video card controller, etc. In addition, it would be recognized that when a general purpose computer accesses code for implementing the processing shown herein, the execution of the code transforms the general purpose computer into a special purpose computer for executing the processing shown herein. Certain of the functions and steps provided in the Figures may be implemented in hardware, software or a combination of both and may be performed in whole or in part within the programmed instructions of a computer. No claim element herein is to be construed under the provisions of 35 U.S.C. 112(f), unless the element is expressly recited using the phrase “means for.” In addition, an artisan understands and appreciates that a “processor” or “microprocessor” may be hardware in the claimed disclosure. Under the broadest reasonable interpretation, the appended claims are statutory subject matter in compliance with 35 U.S.C. § 101.

According to an embodiment, the electronic device 100 may be referred to as a smart phone, a table personal computer (PC), a PC computer, or the like. Referring to FIG. 1 , although the electronic device 100 is exemplified as a smartphone herein, the present disclosure is not limited thereto. For example, in another embodiment, the electronic device 100 may be a wearable device. The at least one processor 110 may include an application processor (AP), a central processing unit (CPU), a communication processor (CP), or the like.

According to an embodiment, the electronic device 100 may be coupled to a wearable device 200, thereby directly controlling the wearable device 200.

According to an embodiment, the communication circuit 120 may be configured to communicate with at least one wearable device 200. The electronic device 100 may form a communication channel with the wearable device 200 through the communication circuit 120 to be connected with the wearable device 200 either via a wire or wirelessly. The electronic device 100 may transmit control signals, data, or the like to the wearable device 200 through the communication circuit 120.

According to an embodiment, the wearable device 200 may include a processor 210, a communication circuit 220, and an actuator 240. Additionally or alternatively, the wearable device 200 may further include a display 230 to provide, for example, visual user interfaces related to haptic feedback. The processor 210 of the wearable device 200 may communicate with the electronic device 100 through the communication circuit 220. The processor 210 may also drive the actuator 240, thereby outputting haptic feedback having a specific pattern.

According to an embodiment, the electronic device 100 may generate a control signal for controlling the wearable device 200 based on the position where the wearable device 200 is placed, and/or information regarding the actuator 240, such as vibration characteristic of the actuator 240, whether the actuator 240 is a linear resonance actuator (LRA), an eccentric rotating mass (ERM) vibration motor, a DC motor, etc. The control signal may then be transmitted to the wearable device 200 so that the wearable device 200 outputs haptic feedback having a specific haptic pattern. The wearable device 200 may then output the haptic feedback having the specific haptic pattern in response to receiving the control signal.

In another example, the electronic device 100 may determine a haptic pattern corresponding to content reproduced or executed and may change the determined haptic pattern into the form (e.g., by changing at least one of amplitude and frequency of the haptic pattern) corresponding to at least one of the position of the wearable device 200 on the user's body and the vibration characteristic of the wearable device 200, such as the type and size of the actuator 240. The electronic device 100 may transmit a control signal corresponding to the changed haptic pattern to the wearable device 200 and the wearable device 200 may output haptic feedback in response to the control signal.

According to an embodiment, the wearable device 200 may operate as a haptic feedback device for the electronic device 100. In this case, the wearable device 200 may disable other operations or functions, for example phone call function, alarm function, biometric sensor signal collecting function, or the like.

According to an embodiment, the electronic device 100 may further include a display 130 and a memory 140. For example, the electronic device 100 may provide several interfaces, which are to be described with reference to FIGS. 5 to 7 , through the display 130. The electronic device 100 may store, in the memory 140, data required to generate the control signal to be transmitted to the wearable device 200.

FIGS. 2A and 2B illustrate an operating environment of the electronic device, according to an embodiment.

According to an embodiment, at least one processor 110 may identify at least one wearable device 200 connected with the electronic device 100. The electronic device 100 may obtain information on the position on the user's body where the at least one wearable device 200 is placed (wearing position).

For example, the information on the position where the wearable device 200 is placed may be referred to as information of a body part of the user where the wearable device 200 is positioned. Referring to FIG. 2B, the wearable device 200 may be put on the head, the neck, the wrist, the chest, the waist, the arm, the hand, the leg, the foot, etc., of the user.

According to an embodiment, an output for a specified haptic pattern may be requested for a particular various function that is executed by the electronic device 100. For example, the specified haptic pattern may correspond to specific content (e.g., images, games, VR content, or the like) reproduced or executed by the electronic device 100. The specified haptic pattern may include information on a part of the body that will receive the haptic pattern, intensity of the vibration, period of the vibration, duration of the vibration etc. The haptic pattern may be previously associated with the content so as to enrich user experience.

According to an embodiment, if the output of the specified haptic pattern is requested as at least one function is executed, the electronic device 100 may control the wearable device 200 such that the wearable device 200 outputs haptic feedback corresponding to the specified haptic pattern. For example, the electronic device 100 may generate a control signal corresponding to the specified haptic pattern and the position where the wearable device is placed and may transmit the control signal to the wearable device 200. The wearable device 200 may output the haptic feedback corresponding to the control signal.

According to an embodiment, the specified haptic pattern may include a position list of the positions where the haptic feedback occurs. For example, the position list may include a plurality of target positions for producing a haptic effect. The electronic device 100 may select the wearable device 200 among various wearable devices based on a particular target position in the position list.

According to an embodiment, even if the same haptic pattern is specified, different haptic feedback may be output depending on where the wearable device 200 is located. That is, the specified haptic pattern may be altered depending on the position on which the wearable device 200 is placed. For example, the electronic device 100 may obtain a setting value for altering the specified haptic pattern based on the wearing position of the wearable device. Then, the electronic device 100 may generate the control signal based on the obtained setting value. The setting value may, for example, be previously stored in the electronic device 100 or received from an external device (e.g. a server).

Referring to FIG. 2A, by way of example, the electronic device 100 is connected with a first device 201 placed on a left arm, a second device 203 placed on the head, and a third device 205 placed on a right hand. The electronic device 100 may identify the first to third devices 201 to 205 when they are connected with the electronic device 100. The electronic device 100 may obtain “the left arm” as position information of the first device 201, “the head” as position information of the second device 203, and “the right hand” as position information of the third device 205.

In one example, as a function (e.g. VR function) of the electronic device 100 is executed, output of a haptic pattern having the same vibration intensity may be requested with respect to the first device 201 to the third device 205. But the electronic device 100 may control the first device 201 to the third device 205 to output different haptic feedback based on the positions of the wearable devices. For example, the electronic device 100 may cause the second device 203 to output vibration having the weakest intensity, because it is placed on the head of the user. That is, due to sensitivities in the head region of the user, to provide tactile sensation of the same intensity as feedback to another part of the body, haptic feedback provided to the head of the user may have to be weaker.

If output of the haptic pattern is requested only with respect to the hand and the arm, on the other hand, the electronic device 100 may transmit control signals only to the first device 201 and the third device 205. Accordingly, a particular tactile effect may be transmitted to only some body parts by the electronic device 100.

FIG. 3A is a flowchart illustrating a haptic operating method for the electronic device depending on positions of the wearable devices, according to an embodiment. FIG. 3B is a flowchart illustrating a haptic operating method for the electronic device depending on vibration characteristics of the wearable devices, according to an embodiment.

Referring to FIGS. 3A and 3B, according to an embodiment, the method for controlling the wearable device 200 may include operation 310 to operation 350. Operation 310 to operation 350 may be performed by the electronic device 100 illustrated in FIG. 1 . Each of the operations 310 to 350 may be implemented with instructions being able to be performed (or executed) by the processor 110 of the electronic device 100. The instructions may be stored, for example, in a computer-recording medium or the memory 140 of the electronic device 100 illustrated in FIG. 1 . In the following description of operations 310 to 350, reference numerals of FIG. 1 are used and descriptions duplicative of those of FIG. 1 will be omitted in order to avoid redundancy.

In operation 310, the electronic device 100 may identify at least one wearable device 200 connected with the electronic device 100. For example, the electronic device 100 may search for and identify the wearable device 200 so that the wearable device 200 is connected with the electronic device 100 for providing haptic output.

In operation 320, the electronic device 100 may obtain information on the position on which the wearable device 200 is placed. If output for a specified haptic pattern is requested as a particular function is executed in the electronic device 100, in operation 340, the electronic device 100 may transmit a control signal to the wearable device 200 such that the wearable device 200 outputs haptic feedback corresponding to the position information and the specified haptic pattern. The descriptions of operation 320 and 340 have been described with reference to FIGS. 2A and 2B.

In operation 330, the electronic device 100 may obtain vibration characteristic information output by the actuator 240 included in the wearable device 200, which is connected with the electronic device 100. In operation 350, the electronic device 100 may transmit a control signal to the wearable device 200 such that the wearable device 200 outputs haptic feedback corresponding to the vibration characteristic information and the specified haptic pattern. For example, the vibration characteristic information may include information on the types of haptic pattern that may be outputted by the actuator 240 based on hardware characteristics of the actuator 240.

According to an embodiment, even if the same haptic pattern is specified, different haptic feedback may be outputted depending on the characteristics of the actuator 240. The frequency band or the reactive speed of the haptic feedback may be different depending on the types of actuators 240. For example, a linear resonant actuator (LRA) may output haptic feedback with shorter periods as compared to a direct current (DC) actuator.

The electronic device 100 may change the specified haptic pattern to a haptic pattern which is able to be outputted by the actuator 240. The electronic device 100 may generate a control signal corresponding to the changed haptic pattern and may transmit the control signal to the wearable device 200.

For example, the electronic device 100 may generate a control signal by using change information for changing the specified haptic pattern such that the specified haptic pattern is differently output depending on the vibration characteristic of the actuator 240. For example, the change information may be stored in the memory 140 of the electronic device 100. In addition, the change information may be received from an external device (e.g., a server).

According to an embodiment, operation 320 and operation 330 may be simultaneously performed. That is, the electronic device 100 may simultaneously process the specified haptic pattern, the position of the wearable device 200, and the vibration characteristic of the wearable device 200. The position information and the vibration characteristic information of the wearable device 200 may be obtained from the wearable device 200. Using the position information and the vibration characteristic information, the electronic device 100 may generate haptic feedback suitable for the position of the wearable device 200 and suitable for the actuator 240. The electronic device 100 may transmit the control signal to the wearable device 200 such that the wearable device 200 outputs the haptic feedback corresponding to the position information, the specified haptic pattern, and the vibration characteristic information.

For example, the electronic device 100 may change the specified haptic pattern, based on the position of the wearable device 200 and/or the characteristic of the actuator 240. Thus, the electronic device 100 can dynamically alter the specified haptic pattern so that proper haptic feedback can be outputted by the wearable device 200 even if different devices with different vibration characteristic are used as the wearable device 200.

FIG. 4 is a flowchart illustrating a method for obtaining position information of a wearable device, according to an embodiment.

Referring to FIG. 4 , according to an embodiment, the method for obtaining the position information of a wearable device may include operation 410 through operation 420. Operation 410 through operation 420 may be performed by the electronic device 100 illustrated in FIG. 1 . Each of operation 410 and operation 420 may be implemented with instructions being able to be performed (or executed) by the processor 110 of the electronic device 100. Hereinafter, reference numerals of FIG. 1 may be employed in the description made with reference of FIG. 4 .

Operation 410 may correspond to operation 310 of FIG. 3A and FIG. 3B. The duplicative description thereof will be omitted.

In operation 415, the electronic device 100 may obtain information associated with the position on the user's body where the wearable device 200 is placed. In operation 420, the electronic device 100 may determine the position of the wearable device 200 based on the obtained associated information, thereby obtaining the position information.

According to an embodiment, the associated information of operation 415 may be motion information of the wearable device 200. The electronic device 100 may obtain position information based on the motion information.

In another example, the electronic device 100 may determine the position of the wearable device 200 based on data obtained through a sensor (e.g., a gyro sensor) of the wearable device 200. The data may include a direction in which the wearable device 200 moves, or the like.

For example, the movement data corresponding to a body part wearing the wearable device and a wearing direction (leftward or rightward) may be previously computed. The electronic device 100 may store the previously computed movement data in the memory 140 or may receive the previously computed movement data from an external device (e.g. a server). The electronic device 100 may compare the previously computed movement data with movement information obtained from the wearable device 200, thereby determining the position of the wearable device 200.

According to an embodiment, the associated information of operation 415 may be user input. The electronic device 100 may obtain the position information based on the input. For example, the electronic device 100 may directly receive an input stating that, for example, the wearable device 200 is placed on the left arm of the user.

According to an embodiment, the associated information of operation 415 may include information on the type of the wearable device 200. For example, the information on the type of the wearable device 200 may be received from the wearable device 200 and may be stored in the memory 140 of the electronic device 100. The electronic device 100 may obtain the position information based on the type of the wearable device 200. For example, when the wearable device 200 is a head-mount device, the electronic device 100 may determine that the wearable device 200 is positioned on the head of the user 50.

According to an embodiment, the electronic device 100 may obtain the position information by using a biometric sensor mounted in the wearable device 200 and bio information obtained from the biometric sensor.

For example, the electronic device 100 may determine the wearing position based on the type of sensor mounted in the wearable device 200. The wearable device 200 including a fingerprint sensor may be determined as being placed on a finger of the user. The wearable device 200 including an iris sensor may be determined as being placed on the face of the user. The wearable device 200 including a heart rate sensor may be determined as being put on a wrist of the user.

For example, the electronic device 100 may obtain position information by using bio information obtained from the mounted sensor. When the fingerprint information is obtained, the wearable device 200 may be determined as being put on the finger. When the heart rate information is obtained, the wearable device 200 may be determined as being put on the wrist.

According to an embodiment, the electronic device 100 may obtain the position information based on the combination of information related to the biometric sensor and the movement information.

For example, when the electronic device 100 obtains information on the heart rate of the user, the electronic device 100 may determine the wearable device 200 as being placed on the wrist of the user. Based on movement data, the electronic device 100 may determine whether the wearable device 200 is placed on the right wrist or the left wrist. Thus, the electronic device 100 may determine the position on which the wearable device 200 is placed by using a combination of biometric information and the movement information.

FIG. 5 is a view illustrating an interface to obtain motion information of the wearable device, according to an embodiment.

According to an embodiment, the electronic device 100 may output a screen for inducing movement of the wearable device 200 through the display 130 of the electronic device 100 or the display 230 of the wearable device 200. The electronic device 100 may determine the position of the wearable device 200 by using movement information obtained.

Referring to FIG. 5 , the electronic device 100 may display the list of wearable devices 200 connected with the electronic device 100 as illustrated through screen 510. Screen 520 includes one example of guide information for inducing the movement of the wearable device 200. The determined position of the wearable device 200 is displayed on a screen 530.

Alternatively, the electronic device 100 may transmit a multiple control signals to all of the wearable devices 200, and each of the wearable devices 200 will extract the control signal corresponding to it from the multiple control signals. Thus, the wearable devices 200 may output different haptic feedbacks having different patterns.
